Xu Da's death and why Zhu Yuanzhang didn't kill Tanghe.

Zhu Yuanzhang killed Xu Da instead of Tanghe, because Tanghe surrendered the military power, and Tanghe did not seek success, so he could treat unfair treatment with a normal heart. Zhu Yuanzhang, who laid the foundation of the country, only named Tanghe Hou, and all other generals and ministers with the same conditions were knighted. However, master Tang is still very cautious. After Tanghe returned to his hometown, he drank and played chess all day. He never made friends with central officials and squires, nor discussed state affairs, giving people an appearance of coveting enjoyment and not caring about the world, which also made Zhu Yuanzhang very relieved.

Why didn't Zhu Yuanzhang kill Tanghe?

Is that he can treat credit correctly. Tang He worked with Zhu Yuanzhang under Guo Zixing in his early years, and he was older than Zhu Yuanzhang. Later, Zhu Yuanzhang stood out and gradually became a leader. Other generals who risked their lives to see Zhu Yuanzhang as the boss were inevitably unconvinced. Although Tang He is only three years old, he is very restrained and Mao is very satisfied with it.

At the critical moment, he took the lead in recognizing Zhu Yuanzhang's leadership position, and Zhu Yuanzhang has always recognized this contribution. He can treat unfair treatment with a normal heart. When he made great contributions to the country, Zhu Yuanzhang deliberately downgraded Tanghe to the first class and found a fault to make him a Hou, while others with the same conditions were publicly titled. He was very cautious, never complained, and continued to serve the emperor conscientiously and on thin ice. He was deeply loved by Zhu Yuanzhang, so he was made a believer a few years later.
